 Because this was merged Oct. 27th: https://github.com/xbmc/xbmc/pull/14701

EDIT: the solution is simple: just whitelist the refresh rates you really need. In general those are only 23.976, 24, 50, 59.94, 60

Just to be clear - you're suggesting the whitelist change is responsible for the mouse cursor appearing?  

No, I said that the whitelist change is responsible for having two resolution changes instead of one. That is the first error that shows in the log. This can easily be fixed by a whitelist that lacks 25hz. We never selected a 25hz mode in earlier version. It could be an issue related to that, I don't know. A new debug log with with this whitelist might tell more.
